unable to install Qiime2 on MacBook M1

I think I have open the Rosetta mode in the terminal, but when I ran this command "conda install wget", I met this error:
CondaValueError: You have chosen a non-default solver backend (libmamba) but it was not recognized. Choose one of: classic

Can you help me?
Thanks

Hello @Yiggrite,

It looks like you have a version of conda that doesn't support the libmamba solver. You can either use conda config --set solver classic or conda update conda and then try installing again.

both did not work.

I installed the Anaconda (the regular version for OSX)
Anything wrong?

Hello @Yiggrite,

Interesting. Can you try uninstalling and reinstalling conda? You could try miniconda rather than anaconda for a quicker installation.
